Nutter, in a statement released Friday (via CSNPhilly.com), called the remark "repugnant, insensitive and ignorant" and a "disgrace." He added that "all of us, regardless of race or nationality, should be offended by these comments."

Nutter stopped short of saying the Eagles should release Cooper, but he said that he would seriously consider terminating any city employee who made a similar comment.

Cooper apologized to his teammates last week for using the N-word during the concert at Lincoln Financial Field. The epithet was caught on video. Some Eagles players, in particular running back LeSean McCoy, aren't sure they can forgive and forget.

Nutter surely isn't in a forgiving mood.

"Mr. Cooper must look deep in his heart to see how, beyond his personal public apology, he can repair the damage that he has caused to the Philadelphia community, and its relationship with the Philadelphia Eagles and the NFL," the mayor said in his statement.

"This incident is a disgrace, and cannot be excused by just paying a fine, as if it were a parking ticket,” he added.
